How Samsung Watches Measure Blood Pressure

Samsung smartwatches that offer blood pressure monitoring utilize Pulse Wave Analysis (PWA) technology combined with optical sensors to estimate blood pressure levels. Unlike traditional cuff-based devices, these watches employ sensors on the wrist to detect the pulse wave traveling through blood vessels. This pulse wave data, when analyzed alongside user-specific calibration values, allows the watch to approximate systolic and diastolic pressure.

Key components involved in this process include:

  • Optical Heart Rate Sensor: Uses photoplethysmography (PPG) to measure blood volume changes in the wrist’s microvascular bed.
  • Pulse Wave Velocity (PWV): Calculated by analyzing the time delay between cardiac contractions and pulse wave arrival at peripheral sites.
  • Calibration Procedure: Users initially calibrate the watch using a conventional blood pressure cuff. This establishes baseline values for accurate estimation during subsequent measurements.

It is important to note that Samsung’s blood pressure feature is designed for convenience and trend tracking rather than replacing medical-grade sphygmomanometers. The accuracy depends heavily on proper calibration and consistent positioning during measurement.
